Results: The Locked Intramedullary Nails group had significantly shorter hospitalization time and time to union than the plates group, which were(9.91+3.4)d versus (12.1+2.7)d and (74.4+7.2)d versus (108.2+8.7)d respectively.

Methods 51 cases of femoral subtrochanteric fractures were treated with reconstruction intramedullary nails in our department in the period from January 1997 to June 2003. Among them 9 cases belonged to Russell Taylor type ⅠA, 26 ⅠB, 2 ⅡA, and 14 ⅡB. 34 patients sustained high energy injury, and 17 low energy one.

The lumbosacral cord of a 55-day baby girl was cut serially and stained for a microscopicstudy.It was twice split into two with extensive dysplasia in its dorsal parts.Numerous primarysensory cells were strewn within the cord.The present study was particularly concerned with theirclassification,distribution and derivation.In addition to their normal sites,the sensory ganglionic cells are scattered on the dorsal aspectsof the cord,along the space between the separated cords,in the openings of the anterior and...

The lumbosacral cord of a 55-day baby girl was cut serially and stained for a microscopicstudy.It was twice split into two with extensive dysplasia in its dorsal parts.Numerous primarysensory cells were strewn within the cord.The present study was particularly concerned with theirclassification,distribution and derivation.In addition to their normal sites,the sensory ganglionic cells are scattered on the dorsal aspectsof the cord,along the space between the separated cords,in the openings of the anterior and posteriormedian fissures and also within the crevices inside the cord,yet communicating to the outside.Such sensory elements are surrounded with capsular cells;this is also characteristic of a few sen-sory cells slightly sunken into the intramedullary structures in continuation with the heterotopicganglionic formations.A number of the sensory cells are deeply embedded in the supernumerary gray and white for-mations chiefly in the dorsal portions;they are especially numerous in the anterior gray commissureand the anterior horn.Such cells are devoid of a capsule.In the early embryonic period,unfavorable conditions retard the mutual approximation of theneural folds and the precocious ectomesenchyme thrusts itself between them.The dorsal edges ofthe folds are then forced to bend ventrally toward the neural plate,resulting in a duplication of thespinal cord.During the rolling-in process,the irregular margins of the neural folds and the out-thrusts ofthe ectomesenchyme conjoin to produce the supernumeraray structures in the dorsal portions of thecord.Some presumptive sensory elements on the folds may be roiled into such intramedullary unitsand grow up in situ.The neural crest represents the spear-head of the rollingin fold;its presumptive sensory ele-ments may well disperse themselves into the precursory anterior gray commissure and theanterior horn.The primarys sensory cells and the capsular cells are both derived from the ectoderm.Theformer bear capsular cells in case they have participated in the process of ganglion formation;whereas they lack such a capsule if they grow up right in their erratic sites.The intraspinal sensory ganglionic cells are chiefly derived from the neural crest;this doesnot exclude the tube wall as being another possible source.Though erratic in postion,the intraspinal sensory cells may perform a fairly normal function.

15 cases of hemoglobin E ( HbE), including 12 cases of HbE-β-thal-assemia and 3 cases of HbE, were reported. Clinical, laboratorial and genetic studies revealed that HbE could be divided into two groups, HbE and HbE-β-thalassemia, the latter being further divided into two types according to HbE contents. HbE-β-thalassemias with HbE content above 45% showed severe clinical symptoms and laboratory findings, while that with HbE content below 45% not,the latter type being called HbE -β+-thalassemia. Ultrastruc-tural...

Ultrastruc-tural studies showed that erythroblasts in bone marrow were irregular inshape with electronic dense inclusion bodies and suggested intramedullary hemolysis. Investigation of family history revealed that this disease was autosomal codominant in mode of inheritance. Authors suggested that this HbE gene might be brought from Guangdong to Sichuan Province more than 300 years ago.

This paper introduces the construction, indication and operative technique of the compressive intramedullary rod. 67 cases of long bone fracture and 3 cases of olecranon fracture have been treated with the compressive intramedullary rod, with a total number of 85 fractures, of which one half belongs to non-union or malunion. 53 cases have finished the treatment and all the fractures heal well. For those of non-union or malunion, the autogenous iliac bone graft at the same operation proves to be benificial....
